BARDSHAR HUMIDIFIER AND TOP OILER FOR INTERNAL-COMBUSTION ENGINES Filed March 1, 1948 INVENTOR ATTORNEYS flJZCBezrd'skar Patented Oct. 17, 1950 f HUMIDIFIER AND TOP OILER Fort INTER NAL-COMBUSTION ENGINES De Yo E. Bardshar, Tacoma, Wash. Application March 1, 1948 Serial No. 12,436 Y 2 Claims. (01. 261-118) Thisinvention relates'to humidifiers and top oilers for internal combustion engines.

An object'of the invention is to provide an improved humidifier and. top oiler adapted to be connected with the Venturi passage in the carburetor of an internal combustion engine.

j Another object of the invention is to provide an automatically operated humidifier and top oiler for connection with'the Venturi passage between the usual choke and throttle valves in the carburetor of ant-internal combustion engine. A further object of the invention is to provide an improved automatically operated humidifier pensive to manufacture and produce.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts, hereinafter more fully described and pointed out in the claims, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

Referring to the drawing 7 Figure 1 is a side elevation of the hood of an automobile with a part thereof being broken away to show the improved humidifier and top oiler supported in operative position on the automobile engine.

Figure 2 is an enlarged side elevation of the improved humidifier and top oiler connected with the venturi of a carburetor, with portions thereof being broken away and in section to show the interior construction thereof.

Figure 3 is an end view of the improved humidifier and top oiler with a part thereof being broken away to show the position of the feed line and hook-shaped needle valve associated therewith. I

Figure 4 is an enlarged detail transverse sectional view through the feed line showing the hook-shaped needle valve for controlling the flow of top 011 into the feed line.

Like characters of reference are used throughout the following specification and the accompanying drawing to designate corresponding parts. g

In carrying out the invention, there is shown an automobile I having a hood 2 underiwhich an internal" combustion engine 3 is disposed. V

The engine 3 is' provided. with a carburetor l of the down-draft type, upon which an air cleaner or filter 5 is supported. The carburetor 4 is formed with the usual venturi 6 and a choke valve land throttle valve 8 disposedrespectively above and below the'venturi 6. As usual, the carburetor 4 will be connectedwith and supported by the'intake manifold 9 of the engine 3.

A supporting frame" In for the humidifier and top oiler is mounted upon the bracket H which in turn is secured by a bolt [2 to any portion'of the engine 3 adjacent the carburetor 4.

The lower surfaceof the supporting frame I0 is secured at .13 to receive and seat the cork gaskets 14 upon which the glass water and top oil containing cups I5 and were firmly held by means of cross arms ll which extend below and contact the bottoms of said cups. I5 and [6. A supporting wire l8 is-connected' at'one .endof each cross arm I! and is connected at its upper end to an eye l9 attached to the supporting frame HJ. attached to the U-shaped arms 2E] between which the hinged hooks 2| areadjustably supported and resiliently tensioned by the coil springs 22. The upperends of the hooks 2| are adapted to be detachably disposed over the eyes 23 attached to the supporting frame I0, thus when released, permitting of the removal and refilling of the cups I5 and I6.

An air intake tube 24 is extended through the frame l0, terminating within and adjacent the bottom of the water containing cup I5.

The feed pipe 25 extends through the frame It] at one end, terminating adjacent the top of the water containing cup 15, and runs above the frame [0 to a point over the top oil containing cup l6, and extends downwardly through the frame ID in the form of a loop 26, and upwardly through the frame l0, where it is again bent to extend across the frame H) to enter through the carburetor 4 with its terminal end 21 bent downwardly and restricted at a point within the venturi 6 between the choke valve 1 and throttle valve 8. I

An inwardly tapering top oil entrance opening 28 is formed through the bottom of the loop 26 of the feed pipe 25, and cooperates with a hookshaped needle valve 29 formed on the lower end.

of the valve stem 30 which is supported at its The opposite ends of the cross arms [1 are 3 upper end by the coil spring 3| disposed about the collar 32 which in turn is attached to the lug 33 secured to the under surface of the frame 10 by means of the screw 34.

An adjusting screw 35 is threaded through the collar 32 and extends through and above the frame ID for selectively adjusting the needle valve 29 to the 'desiredadjustment.

From the foregoing description, it will be seen that when water is placed in the cup l5 and top oil is placed in the cup [6 and the valve 29 adjusted, the operation of the humidifier and top oiler is entirely automatic, being "controlled by the operation of the throttle valve "8. Air will enter through the air inlet pipe or tube and the suction from the carburetor 4 will humidify the air which will pass through'tl'ie feed pipe 25 and will pick up top oil to be fed into the venturi 6 of the carburetor 4.
